Mump 1002 17 O 1965 Ford Mustang Fastback Main Power 70 Amp Fuse

Main power begins at a 70-amp fuse, which serves as main circuit protection. Although the Painless 14-circuit system has fuses and breakers for each circuit, the redundancy of a main fuse is critical in case there's ever a solid short to ground somewhere in the system. When the 70-amp fuse lets go, it disables everything, stopping your Mustang dead in its tracks but preventing a roadside inferno.
